In this work, the worn-out lead pastes of the seriously softened positive lead plates of a lead acid battery are, for the first time, successfully recovered to be lead powder using a facile method of carbon black-present calcination. Namely, the mixtures containing the worn-out lead pastes and carbon black are calcine…
The FeCo@SiO 2 /holey reduced graphene oxide composite was successfully prepared by combining liquid-phase reduction reaction in argon atmosphere with high-temperature calcination. The FeCo@SiO 2 /holey reduced graphene oxide composite was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, vibrating…
Magnetic polariton resonance, standing wave, and their coupling have provided interesting and exotic characteristics for infrared metamaterial. In this paper, the metal-insulator-metal metamaterial absorbers consisting of either single layer dielectric or bilayer dielectrics are discussed to reveal the geometric and d…
Tuning the photoactive behavior of transition metal oxide (Ti <sub>2</sub> O <sub>4</sub> , V <sub>2</sub> O <sub>5</sub> , Zn <sub>3</sub> O <sub>3</sub> ) cluster units by structural modifications with polythiophene.
The structural and nonlinear optical properties of a new anilinium hybrid crystal of chemical formula (C 6 H 7 NCl + ·NO 3 − ) 3 have been investigated. The crystal structure was determined from single-crystal X-ray diffraction measurements performed at a temperature of 100 K which show that the compound crystallizes…
The conductive polyaniline (PANI) electrode materials with different morphologies were prepared by micro-emulsion polymerization with dodecylbenzene sulfonic acid (DBSA) as the dopant and surfactant, and ammonium persulfate (APS) as the oxidant. The concentration of DBSA was crucial in tailoring the morphology of PANI…
Mononuclear zeolite-anchored Rh(CO) <sub>2</sub> complexes do not facilitate NO reduction with CO and groups of rhodium atoms are required to initiate and sustain NO/CO catalytic transformations.
A mixed valence compound, sodium titanium oxide bronze (NaxTiO2-B), combines intriguing properties of high electric conductivity and good chemical stability together with a unique one-dimensional tunnel crystal structure available for cation storage. However, this compound has not been studied for a long period becaus…
Producing light fuels from heavy oil by means of partial oxidation (POX) is a potential method. Chemical looping POX (CLPOX) process using active oxygen species from metal oxides can avoid the direct contact between hydrocarbon molecules and air. The key of CLPOX is the selection of oxygen carrier. In this study, biva…
A thorough investigation of a polymer was performed for corrosion of mild steel in 1M HCl solution using electrochemical and surface studies. Infra-red spectroscopy was completed in reflectance mode to detect the adsorption of the polymer on the metal surface. Scanning electrochemical microscopy (SECM) studies were ma…
Purpose This study aims to investigate the corrosion inhibition effect of extracted oil from Ziziphus lotus fruit on corrosion of C38 carbon steel in 5.5 M H 3 PO 4 solution using potentiodynamic polarization and impedance techniques. Design/methodology/approach Oil composition was determined using gas chromatography,…
Abstract We elucidate the magnetic phases and superconducting (SC) transition temperatures ( T c ) in Sr 2 VFeAsO 3− δ (21113V), an iron-based superconductor with a thick-blocking layer fabricated from a perovskite-related transition metal oxide. At low temperatures ( T < 37.1 K), 21113V exhibited a SC phase in the…
Abstract A peripherally strapped [28]hexaphyrin takes a rectangular conformation and exhibits antiaromatic character. A cyclophane‐type dimer consisting of such [28]hexaphyrins was synthesized from hexakis(pentafluorophenyl) [26]hexaphyrin via S N Ar reaction with allyl alcohol, one‐pot intra‐ and intermolecular olefi…
The influence of substrate type in boosting thermoelectric properties of co-evaporated Bi2Te3 and Sb2Te3 films (with 400 nm-thick) is here reported. Optimized power factor values are 2.7 × 10−3 W K−2 m−1 and 1.4 × 10−3 W K−2 m−1 for flexible Bi2Te3 and Sb2Te3 films, respectively. This is an important result as it is a…
Abstract The solid‐state reaction was adopted to prepare a series of LiCo 1− x Mg x O 2 powders doped with different amount of Mg 2+ . The XRD patterns reveal single phase for all the prepared materials. The shift of the electronic structure of LiCo 1− x Mg x O 2 has been investigated by X‐ray photoelectron spectrosco…
A new BiS <sub>2</sub> -based superconductor was synthesized and its crystal structure was investigated.
Our scanning tunneling microscopy (STM) study observes, for the first time, twin domain boundary (TDB) formations on the surface of WTe 2 single crystal, which is glued by solidifying indium to Si substrate. In these TDB regions, a large inhomogeneous strain field, especially a critical shear strain of about 7%, is ob…
Abstract The structure, magnetic and ferroelectric properties of sputtered epitaxial CoFe 2 O 4 -BiFeO 3 (CFO-BFO) nanocomposite thin films grown on La 0.7 Sr 0.3 MnO 3 (LSMO) layers on (001) oriented SrTiO 3 (STO) substrates and on STO-buffered Si are described. The as-grown LSMO thin films were smooth and poorly con…
Abstract The preset study was undertaken to determine solubility and solution thermodynamics of a novel anticancer drug baricitinib in some pharmaceutically used mono/pure solvents including “water, ethanol, polyethylene glycol-400 (PEG-400), ethyl acetate (EA), dichloromethane (DCM) and dimethyl sulfoxide (DMSO)” at…
Reduced molybdenum oxide, generally MoO 3– x, becomes increasingly metallic as the oxygen level decreases during the reduction of MoO 3 to MoO 2 . Its interesting properties have recently intrigued research on MoO 3– x in electrical and electrochemical areas. Lacking effective tools to control the oxygen level is one…
